TYP BAR FOR STENOGRAPHIC TYPEWRITERS.

Application filed August 28, 12322. Serial No. 584,699.

lTo all whom t may concern Be it known that l, EDNA G. RonnsoN, a citizen of the United States, residin T at Tieltlanta, in the county of Fulton and tate ot Georgia, have invented certain new and useful Improvements in Type Bars for Stenographic Typewriters, or" which the following is a specification. l

The invention relates. to stenographic typewriters, and vhas as an objectthe provision -of a type bar bearing a pluralityoic type' and a plurality of keys, each of which may operate'its corresponding type. Af'urther object ot the invention is vthe provision of a type bar having a guide to'enable the linger of the user to be positioned without use of the eyes. I

An illustrative embodiment of the invention is shown in the accompanying drawing*z in whichig. 1 is a side View of a single bar;

Fig. 2 is a detail side view of .an element ofthe bar, and

Fig. 3 is a plan view of the structure shown in Fig. 1;

Fig. 4 is a detail vertical longitudinal section on yan enlarged scale, and 4 Fig.' 5 is adetail vertical transverse section on lino@V .-of Fig. 1.

In the sten'oguaphic typewriter it is desirable to have only ten keys on the machine that one key may be operated by each inger or thumb. However, the provision o i ten lletters is not sutlicient. The present inven- .tion provides a plurality of characters upon 4each type bar, each character operable by the pressing of the corresponding key. To this end there is shown in the drawings a bar 10, pivoted at 11, and a second-bar 12 pivoted yupon the bar 10, as at 13. The bar 12 will be referred to as a type bar.

A plurality of type 11 are shown as mounted upon the vertical elongated end 15 orn the. type bar 12. If the bar 10 be moved about the pivot 11, ,the type 14: which is brought to the printing line opposite the center ,of a roll 16 bearinr paper, shown in dotted lines, will be pressed toward the paper and an impression made, an inked ribbon 'being interposed between the type and the paper.

To move the bar 12 about the pivot 12 a plurality of keys 17 are provided, each pivoted upon a pin 18 upon the bar 10. To hold the keys vin normal position a relatively light spring 19 is secured to the upper portion of the bar 10 and extends under the horizontal portion 2O of each key. The means for moving the part 12 may be omitted from the end key 21 since the type 1l corresponding to said key is normally placed upon the printing line. However. this key is provided with a spring 19 so that the Feel of the key and its yielding may be exactly the sume as is the case with the other keys 17.

Projecting from the bar l2 through openings 22 in the bar 10 there are shown pins 23, preferably formed integral with the bar 12. As shown the pins 23 lie directly under portion 2O ot each key. ,The spring 19 maybe interposed between the top of the pins 23 and the horizontal portion 2O of the key it desired.

To hold the bar l() in its normal position a relatively stiff spring 2e may be placed under the end of the bar and seated upon any desirable base. Upon the first pressure oi the key 17 or 21 the relatively light spring 19 will be overcome, and in the case of keys which will be the correct distance to raise the type corresponding to the key depressed to the printing line before the movementabout vthe pivot 11 takes place.

Itis desirable to have some means to preserve contact ot the inger of the user with the row of keys. To thls end there is pro- 'vided a plate-like member 25, shown as pivoted at26 upon the bar 10, and as having a projecting portion 27 overlying the last projection 23 upon the type bar 1 2, thereby act- .ingas a key. it is preferred lto place a letter which is used with more frequency than, are the letters upon the other keys 17 upon the member 25, or upon the plate 27, .since the finger can be lifted to the top of the member 25 at any position upon the row of keys, and thereby cause the character corresponding to the key 27 to be actuated with a minimum of movement of the finger.

The bars as shown in Fig. 3 may be bent into an angle, as at 28 and 29, which angles may vary according to the necessity of placing a bar in a machine with other like keys, which vary from that shown pierely by the characters chosen and by the angles, which member to move said t will depend upon the position of the key in the machine.

lt will be seen that the type desired may he actuated in the most simple manner by a simple pressure thereon, the aet of selecting the type and making;r the impression being entirelyY automatic without an v care on the part ot' the operator as to the nature of the pressure applied or as to .any other feature than the pla'chip4 ot' the fingers upon the ronrect key.. v

rlhe type bar l2 may be returned to normal b v gravity after each actuation or :i light springsr .'tlmaybe i'iiteip sed between the bars l() and 12 tor thc purpose.
